I tried tmux for a while but I went back to screen because it's super basic enough for me :D

I migrated to Firefox for the same reason, I also use it on my Android with sync between them. I keep Chrome around for testing and for Google Hangouts/Meet that doesn't work on Firefox :-( - the developers tools are great, I just miss Lighthouse (which is from Google :D).

Didn't know about Figma, thanks for the tip! It must be a huge React app...
